Common fate,game harmony and contributions to public goods: experimental evidence

We experimentally study the effects of common fate on voluntary contributions to linear public goods. In each period, earnings are assigned to subjects according to the outcome of a lottery. In ‘common fate’, ‘independent fate’ and ‘rival fate’ treatments, the lottery outcomes of group members are (respectively) positively correlated, stochastically independent and negatively correlated. We observe the highest contributions and strongest reciprocity under common fate. Contrary to the game harmony hypothesis, contributions are not lower under rival fate than under independent fate. Surprisingly, under rival fate, having won the lottery in one period induces higher contributions in the next period.     

Commitment and matching contributions to public goods

We study multi-stage processes of non-cooperative voluntary provision of public goods. In the first stage, one or more players announce contributions that may be conditional on the subsequent contributions of others. In later stages, players choose their own contributions and fulfill any commitments made in the first stage. Equilibrium contributions are characterized under different assumptions about the commitment ability of players, the number of public goods and whether players commit to matching rates or to discrete quantities. We focus on contribution mechanisms that can emerge and be sustainable without a central authority, and that may be particularly relevant for international public goods. Efficient levels of public goods can be achieved under some circumstances, while in others commitment is ineffective.     

Religion,administration & public goods: Experimental evidence from Russia

In this paper, I argue that religion matters for the provision of public goods. I identify three normative foundations of Eastern Orthodox monasticism with strong economic implications: 1. solidarity, 2. obedience, and 3. universal discipline. I propose a public goods game with a three-tier hierarchy, where these norms are modeled as treatments. Obedience and universal discipline facilitate the provision of threshold public goods in equilibrium, whereas solidarity does not. Empirical evidence is drawn from public goods experiments run with regional bureaucrats in Tomsk and Novosibirsk, Russia. The introduction of the same three norms as experimental treatments produces different results. I find that only universal discipline leads to the provision of threshold public goods, whereas solidarity and obedience do not. Unlike in Protestant societies, in Eastern Orthodox societies free-riding occurs at lower than at higher hierarchical levels. Successful economic reforms in Eastern Orthodox countries start with the restructuring of the middle- and lower-ranked public sector. Authoritarian persistence is defined by the commitment of the dictator to overprovide public goods.     

Leadership and motivation for public goods contributions

Results from a leader–follower public goods game are presented. An individual, when randomly selected to make a contribution knowing others will observe the selection, gives more than in the simultaneous‐move public goods game. Followers adopt a quasi‐matching strategy where they systematically donate less than the leader, but contribute more when the leader does and contribute less when the leader free rides. The net result is increased provision of a public good when contributions are sequential. The results highlight that psychological preferences, rather than solely social preferences, can explain behavior.     

Consistent conjectures and voluntary contributions to public goods: why the conventional theory does not work

The conventional theory of voluntary contributions to public goods assumes that each person maximises his utility taking other people's behaviour as given (Nash conjectures). It is now coming to be recognised that this theory is inconsistent with observed behaviour. This paper argues that the problems of the theory are compounded — and not, as some economists have argued, resolved — by relaxing the assumption of Nash conjectures. If individuals' conjectures are consistent, each person will hold the (correct) belief that other people's contributions are inversely related to his own. Under most reasonable assumptions, equilibrium is a state in which no-one contributes anything.     

The political economy of public goods: Some evidence from India

We are interested in how public goods get allocated by a centralized state. We use data on public goods and social structure from parliamentary constituencies in rural India to understand the allocation of these goods over the 1970s and 1980s. National policies and political agendas during this period emphasized universal access to basic amenities and financed a rapid expansion in rural infrastructure. We find evidence of considerable equalization in many of these facilities, reflecting perhaps the importance of these commitments. Among the historically disadvantaged social groups, those that mobilized themselves politically gained relative to the others. Measures of social heterogeneity that have been emphasized in the recent empirical literature on public goods are relevant but not overwhelming in their importance.     

Demand for different types of public goods: evidence from Nigeria

Preferences of Nigerian households vary across different types of public goods. For example, some prefer roads while others favor education even after controlling for the existing supply of these goods. What explains this variation? We argue that the perceived distributional consequences of specific public goods differ conditional on the personal characteristics of households. In particular, households demand the type of public good that (a) increases the utility of assets they already own and (b) resonates with their past experiences involving the lack of particular public goods. We test our argument with data on 123,000 Nigerian households. We find strong evidence for our argument across six types of public goods.     

Earmarking lottery proceeds for public goods: Empirical evidence from U.S. lotto expenditures

This study examines motives for lottery play using a state-level panel of lottery expenditures. We find that expenditures per capita are greater in states that earmark proceeds for public goods. Further, we find that casino gambling only impacts lotto play in general fund states.     

Experimental approach to the determination of the demand for public goods

The paper proposes a new method of estimating the demand for public goods in view of the ‘free rider’ problem. The idea is to establish an experimental setting in which only a random sample of the population is investigated. Alternative experiments are then proposed with the intent of discovering the true individual demand. First a statistical method is proposed to estimate the bias in response. Then, a random environment is created and it is shown under what conditions a successful elicitation of the demand is possible.     

Individual contribution to public goods

This letter presents an attempt to provide a theoretically satisfactory rationale for expecting free-riding, in the presence of public goods, to be less extensive than the pure theory might suggest.     

Experimental approach to the determination of the demand for public goods: A comment

The paper argues that the Kurz experiments to elicit demand schedules for public goods will yield biased information if they are repeated. An alternative procedure is proposed.     

Hot vs. Cold: Sequential Responses and Preference Stability in Experimental Games

In experiments with two-person sequential games we analyze whether responses to favorable and unfavorable actions depend on the elicitation procedure. In our hot treatment the second player responds to the first player's observed action while in our cold treatment we follow the strategy method and have the second player decide on a contingent action for each and every possible first player move, without first observing this move. Our analysis centers on the degree to which subjects deviate from the maximization of their pecuniary rewards, as a response to others' actions. Our results show no difference in behavior between the two treatments. We also find evidence of the stability of subjects' preferences with respect to their behavior over time and to the consistency of their choices as first and second mover.     

Attributing technological bias to public goods

This note reports a modification of one use of the translog production function reported by Binswanger (1973, 1978). The method employed in this study recognizes that changes in factor shares over time are affected by a variety of decision variables including research and extension. In addition, some of the changes attributed to technical change may in fact be due to a change in the resource environment the individual decision maker faces, including the stock of public goods infrastructure. The study also investigates shifts in technological change which may be attributed to changes in the political climate.     

Collusion as public monitoring becomes noisy: Experimental evidence

This paper uses laboratory experiments to test the implications of the theory of repeated games on equilibrium payoffs and estimate strategies in an infinitely repeated prisoners' dilemma game with imperfect public monitoring. We find that subjects' payoffs (i) decrease as noise increases, and (ii) are lower than the theoretical maximum for low noise, but exceed it for high noise. Under the assumption that the subjects' strategy uses thresholds on the public signal for transition between cooperation and punishment states, we find that the best fitting strategy simply compares the most recent public signal against a single threshold.     

Sequential vs. single-round uniform-price auctions

We study sequential and single-round uniform-price auctions with affiliated values. We derive symmetric equilibrium for the auction in which k₁ objects are sold in the first round and k₂ in the second round, with and without revelation of the first-round winning bids. We demonstrate that auctioning objects in sequence generates a lowballing effect that reduces the first-round price. Total revenue is greater in a single-round, uniform auction for k=k₁+k₂ objects than in a sequential uniform auction with no bid announcement. When the first-round winning bids are announced, we also identify a positive informational effect on the second-round price. Total expected revenue in a sequential uniform auction with winning-bids announcement may be greater or smaller than in a single-round uniform auction, depending on the model's parameters.     

Optimal tax treatment of private contributions for public goods with and without warm glow preferences

Tax-favored contributions for financing some public goods may be a useful part of optimal nonlinear income tax and expenditure policy. There are two sides to the potential gain from subsidized donations. First, for a given level of public good provision, higher private donations from high earners than low earners eases the incentive compatibility constraint for donors and so can raise social welfare. This follows since considering a lower-paid job includes a perception of a drop in public good provision. Second, private donation reduces consumption, easing the resource constraint. This paper explores optimal policy, using first a model with standard preferences and then a model with a warm glow of giving. In addition to showing the conditions for the level of public goods, the paper considers the pattern of optimal subsidization across earnings levels. Analysis of optimal taxation with warm glow preferences is sensitive to the choice of preferences that are relevant for a social welfare evaluation. After considering optimal rules with formulations of social welfare which do and do not include warm glow utility, the paper considers the choice of normative criterion. Like the earlier literature, this paper assumes that organizing private donations is costless while tax collection has a deadweight burden. Since private charitable fundraising is very far from costless, the paper is an exploration of economic mechanisms, not a direct guide to policy.     

National goods versus public goods: Defense,disarmament, and free riders

Tyler Cowen, David Friedman, Marshall Fritz, M. L. Rantala, David Ramsay Steele, Richard H. Timberlake, Jr., David J. Theroux, and Lawrence H. White all gave helpful comments on drafts. They do not necessarily share my conclusions, however, and I alone am responsible for any remaining errors. Aversion of this paper was first delivered at the annual meeting of the Western Economic Association in San Francisco in July, 1986.     

Decentralizing development: Allocating public goods via competition

Decentralizing the allocation of public goods by giving funds directly to communities takes advantage of local information concerning needs, but leaves funds open to misuse or capture by local elites. A large scale development project in Indonesia attempts to overcome this downside of decentralized allocation by having communities compete locally for block grants. Competition weeds out less efficient projects. Increasing the number of villages bidding by 10% leads to a 1.8% decline in road construction costs. Increased community participation in project planning also leads to better outcomes.
